The mpc8569 PowerTM processor is mounted on PB board. + +Building U-boot +----------- + make MPC8569MDS_config + make + +Memory Map +---------- +0x0000_0000 0x7fff_ffff DDR 2G +0xa000_0000 0xbfff_ffff PCIe MEM 512MB +0xe000_0000 0xe00f_ffff CCSRBAR 1M +0xe280_0000 0xe2ff_ffff PCIe I/O 8M +0xc000_0000 0xdfff_ffff SRIO 512MB +0xf000_0000 0xf3ff_ffff SDRAM 64MB +0xf800_0000 0xf800_7fff BCSR 32KB +0xf800_8000 0xf800_ffff PIB (CS4) 32KB +0xf801_0000 0xf801_7fff PIB (CS5) 32KB +0xfe00_0000 0xffff_ffff Flash 32MB + + +Flashing u-boot Images +--------------- + +Use the following commands to program u-boot image into flash: + + => tftp 1000000 u-boot.bin + => protect off all + => erase fff80000 ffffffff + => cp.b 1000000 fff80000 80000 + + +Setting the correct MAC addresses +----------------------- +The command - "mac", is introduced to set on-board system EEPROM in the format +defined in board/freescale/common/sys_eeprom.c. we must set all 8 MAC +addresses for the MPC8569MDS's 8 Ethernet ports and save it by "mac save" when +we first get the board. The commands are as follows: + => mac i NXID /* Set NXID to this EEPROM */ + => mac e 01 /* Set Errata, this value is not defined by hardware + designer, we can set whatever we want */ + => mac n a0 /* Set Serial Number. This is not defined by hardware + designer, we can set whatever we want */ + => mac date 090512080000 /* Set the date in YYMMDDhhmmss format */ + + => mac p 8 /* Set the number of mac ports, it should be 8 */ + => mac 0 xx:xx:xx:xx:xx:xx /* xx:xx:xx:xx:xx:xx should be the real mac + address, you can refer to the value on + the sticker of the rear side of the board + */ + ..... + => mac 7 xx:xx:xx:xx:xx:xx + => mac read + => mac save + +After resetting the board, the ethxaddrs will be filled with the mac addresses +if such environment variables are blank(never been set before). If the ethxaddr +has been set but we want to update it, we can use the following commands: + => setenv ethxaddr /* x = "none",1,2,3,4,5,6,7 */ + => save + => reset + + +Programming the ucode to flash +--------------------------------- +MPC8569 doesn't have ROM in QE, so we must upload the microcode(ucode) to QE's +IRAM so that the QE can work. The ucode binary can be downloaded from +http://opensource.freescale.com/firmware/, and it must be programmed to +the address 0xfff0000 in the flash. Otherwise, the QE can't work and uboot +hangs at "Net:" + + +Please note the above two steps(setting mac addresses and programming ucode) are +very important to get the board booting up and working properly. + |
